"Clearly what we already do still may not be enough," Commissioner Bettman said.
The NHL currently allows for coaches to challenge goals scored off potential offside or goalie interference plays, but Commissioner Bettman acknowledged some controversial plays in the Stanley Cup Playoffs require the consideration to expand what is allowed to be reviewed.
He specifically mentioned San Jose Sharks defenseman Erik Karlsson's overtime goal in Game 3 of the Western Conference Final that was scored after a hand pass in the Blues zone from Timo Meier to Gustav Nyquist was missed by the on-ice officials.
That goal was not allowed to be challenged or reviewed under the current NHL rules for video replay.
"The ability to review and parse plays down to the millisecond has become both a blessing and a curse," Commissioner Bettman said. "If we are to extend video replay, and we will be looking at that possibility, we must find the right balance when it comes to how much more to use and when to use it without affecting the flow, pace and excitement of our game. Perhaps most important, we've got to have a system that enables us to be consistent. This is the challenge, and it's a challenge we are focused on and we will meet."
Commissioner Bettman said the NHL will gather suggestions and ideas from general managers and the Competition Committee, which is comprised of a cross-section of people across the League, before taking any action.
Rule changes require the approval of the GMs, the Competition Committee and the Board of Governors.
The Competition Committee is scheduled to meet June 11, Deputy Commissioner Bill Daly said. The GMs and the Board of Governors will meet later in the month.
"What we have to do is make sure we have feedback from all of the constituent groups, both in terms of soliciting ideas and ultimately whatever conclusion we reach to make sure everybody buys into it," Commissioner Bettman said. "We all understand the issues at the League office. We know what works. We know what doesn't work. We understand the challenges of implementation. So we're going to use that body of knowledge, share it with everybody, and take as much feedback as we can from everyone."
